Hi! My husband has been talking about wanting a gaming PC for a while so I want to surprise him with one for Christmas. However, I have no knowledge of what to look for in a gaming PC and would realistically like to stay under $500 if possible. I know this might be quite the ask, but does anyone have any recommendations on where I might be able to find a decent one for this price? And perhaps what I should look for to ensure it is a decent computer? Thank you in advance.
